TOfALL WHOM IT MAY CONCERN:

Be it known that I, JOHN W. BURNS, of Henry, in the county of Marshall, and State of Illinois, have invented a new and improved Brick Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, which will` enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates` tov a new and improved machine for moulding and pressing brick, and it consists in a novel manner of operating the plungers by which the ground or tempered clay is forced 4into the moulds. and also in a novel arrangement of the plungers .with the mud-mill, whereby the clay may be moulded and pressed into bricks very expeditiously and in a perfect manner. In the accompanying sheet of drawings- Figure 1 is a. front elevation ot" my invention. l

Figure 2, a side view ofthe same, partly in section, as indicated by the line :n x, iig. l.

Figure 3, a vertical central section of the same,l taken in the line y y, iig. 4.-.

Figure 4, a horizontal section ofthe same, taken in the line zk z, iig. l.

Figure 5, a detached horizontal section of a mould, taken in the line a e', iig. 1.

Similar letters of reference indicate like parts.` l

A represents the mud-mill, which may be of cylindrical or other form, and is placed upon a hollow base, B, showniin'iigs. 2 and 3. C is a vertical shaft placed centrally in the mud-mill, and having horizontal arms a projecting radially from it, and also pressers a attached to its loiver part, the presser-s being of spiral forni, and working over openings b b, iii thelbottom of the mud-mill, and forcing the clay through said openings into the moulds. The mud-mill has stationary or fixed bars, b', secured,horizontally in it, and at such points as to admit of the arms a, while rotating, just clearing them. The shaft C has a sweep, l), attached to'it near its upper end, and to the shaft, -below the swecpl), an arm, E, is secured, the use oi' which will be presently shown. Through the hollow base B of the machine, a shaft, F, passes,"having an arin, c, at each end. These arms project from the shaft F in opposite directions, and each arm is connected by a link, d, with an upright rack,` G. These racks are fitted insuitable guides at the exterior of the muri-mill, at opposite sides thereof, and into each rack a pinion or toothed segment, H, gears, said pinions or segments being provided each with an arrn, e. To the shaft F, within the hollow base B, two plungers II are attached by linksf. These plnngers are at opposite sides of the shaft F, and-they extend the Whole length or width of the base B, and work underneath the opezi ings b b, in the bottom of the mud-mill, and force the cla-y into moulds J, which are placed on beds, K K, of

friction-rollers at opposite sides of the mud-mill. The openings in thelbase B, through which the clay is pessed,

into the moulds, are provided with vertical bars, which are in line with the partitions of the moulds J, where the latter are placed in position to receive the clay, and the compartments of' the moulds are provided with plunger.;

Ii, each of which is provided with a projecting stc1n,a bar, M, passingthrough the stems of the plungcrs 'of cach mould, as shown clearly in tig. 5. The empty mouldsare shoved alongv opposite thc openings in the base B, Where they receive the clay, and the filled moulds discharged therefrom, by means of a rack, N, operated by'a pinion, O, having a handle or lever, P, attached, the inner end of the rack having an iipright head, ia, to beur against the mould infront of it, (see fig. I.) `Each bed K is provided with a rack, N, but only one is shown in fig. 4. 4 'Ihc clay, properly moistened, is thrown into the mud-mill, where it is thoroughly ground and tempered, and the pressers a' atforee the same through the openings b int-o the base I3, in front of the plunger-s I I, which alternately force thc clay into the moulds. The plungers I I are operated by the turning of the shaft F, which is accomplished by the arm E, on the shaft e, coming 'in contact with the arms e ofthe pinions or segments H, the shaft F being turned first inone direction and then in the other, so that the plungcrs I I will be operated alternately. By this machine brick may be moulded and pressed with the greatest facility, and in a perfect manner.

-Having thus described my invention, I cla'inras new, and desire to secure by Letters Patentl. Operating the plungers I I, through the medium ofthe shaft F, connected by arms and links to vertical racks G, pinions or segments II, provided with arms e, and the arm E, on shaft C, all being arranged substantially as herein shown and described.

The arrangement of the lnurl-inill A, plungcrs I I, and moulds d', substantially as herein slet forth.

3. The feeding ofthe empty moulds to receive the clay, and the discharging of the filled moulds from the press, by means ofthe'fracks N, and pinions O, substantially as shown and described.
